The 10 dirtiest things in your house

4 The pet food station
If you leave it dirty, you risk your pet ingesting spoiled food. You may also attract ants, roaches or mice.

Cleaning 411:
• Promptly wipe up spilled food or water.
• Wash bowls regularly.
• Protect flooring by placing bowls on a washable placemat or charger plate.

5 The area around the cat litter box
After all, where does kitty step right after she's done her business in her loo?

Cleaning 411:
• Vacuum, then wipe down/mop with vinegar and hot water.
• Alternatively, lay a washable car mat by the litter box. Wash with hot water and dish detergent as needed.

6 Doorknobs
"This actually depends on how vigilantly people in the home wash their hands," says Anne.

Cleaning 411:
• If you have small kids, wipe down knobs as needed or weekly (use a rag and hot soapy water or wet wipes).
• Otherwise, wipe down knobs whenever you clean your baseboards (more frequently on bathroom doorknobs).
